Hi,
Support, feel free to ignore this message, but if anyone has an idea please let me know.
I am working on having a set of SyntaxEditor's share the same scroll bar. Basically we are stacking a few syntax editors in the same parent panel, when one editor gets taller it pushes down the editors below. This link points at a screen shot of my editors. The problem is typing in one of the syntax editors does not scroll the parent panel. I found an article on scrollbars on code project. I put some code into my editor like this:The "AutoScrollVerticalPosition" property calls some Win32 methods like this:
It works ok for the first few returns, but eventually it quits scrolling down. Does anyone have an idea what I am doing wrong?
thanks,
Jake
